Chemical kinetic and photochemical data for use in stratospheric modelling [PDF]

open access: yes
An evaluated set of rate constants and photochemical cross sections were compiled for use in modelling stratospheric processes. The data are primarily relevant to the ozone layer, and its possible perturbation by anthropogenic activities.

Ultra‐High Friction and Adhesion in Hydrogel Layer Driven by Wet‐to‐Dry Transition Dynamics

open access: yesAdvanced Science, EarlyView.
This work reveals a critical wet‐to‐dry transition in polyacrylamide hydrogel layers that induces volumetric shrinkage, resulting in enhanced interfacial contact and dramatically increased friction and adhesion. Leveraging this transition enables strong, reversible gripping on diverse surfaces, offering new insights for hydrogel‐based gripping ...

Unanticipated Interfacial Redox Reaction in the NiOx Transport Layer of Perovskite Light‐Emitting Diodes

open access: yesAdvanced Science, EarlyView.
This study presents the unanticipated interfacial redox reaction between NiOx and perovskite, which is characterized by XPS. This redox reaction is one of the primary reasons for the bias‐induced instability of PeLEDs and is particularly suppressed by simply applying an interface layer between NiOx and perovskite.

High altitude reconnaissance aircraft [PDF]

open access: yes
At the equator the ozone layer ranges from 65,000 to 130,000 plus feet, which is beyond the capabilities of the ER-2, NASA's current high altitude reconnaissance aircraft.

Electrochemiluminescence Drives Photodynamic Therapy In Vivo

open access: yesAdvanced Science, EarlyView.
Electrochemiluminescence (ECL)‐driven photodynamic therapy (PDT) for in vivo cancer treatment is reported for the first time. The flexible ECL patch exhibits stable and intense luminance under alternating current voltage, enabling efficient photosensitization to generate reactive oxygen species that damage cancer cells, thus leading to significant ...

Quasi‐Periodic Porous Structures‐Based Temperature and Pressure Dual‐Mode Electronic Skin for Material Cognition

open access: yesAdvanced Science, EarlyView.
A quasi‐periodic porous structure‐based temperature and pressure dual‐mode electronic skin was proposed. Benefiting from the quasi‐periodic porous structure, the temperature and pressure sensing performance of the electronic skin can be precisely constructed and optimized by changing the size of the porous structure. By analyzing the thermoelectric and
